SEAM-PRESSING MACHINE.

SPECIFICATION forming part of Letters Patent No. 414,754, dated November 12, 1889.

Application filed June 12, 1889. Serial No. 318,981. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES W. CoLLYER, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Seam-Pressing Machines, of which the following is a specification.

My invention relates to machines for pressing or flattening seams of stitched leather goods, and is in the nature of an improvement upon the machine heretofore patented to me.-

The presentinvention consists, essentially, in so constructing the machine that one roll or wheel may readily yield to adapt itself to irregularities in the material passing between it and its companion roll; in the employment of a flexible shaft for said roll, whereby it is enabled to yield; in regulable gage and pressure devices, and in the employment of removable and interchangeable rims or bands for one or both rolls or wheels, whereby the machine may be quickly adapted for different classes of Work. I

In the annexed figures, Figure 1 is a perspective view of my improved machine; Fig. 2, a front end or face. View; Fig. 3, a vertical transverse section taken immediately back of the pressing-wheels; Fig. 4, a perspective view of the seam-guide; Fig. 5, a detail view of the flexible shaft, and Fig.6 a perspective view of the removable loop or band for the working-roller.

The objects of my invention are to simplify the construction and improve the action of this class of machines, and particularly to make such provision for variations in the stock and for knots, cross-seams, &c., as shall effectually guard against injury to the work or to the machine. To this endI make those parts which are subjected to strain or press themselves to the abnormal conditions as they arise. The manner in which such provision is made, or, in other words, the preferred embodiment of my improvements, will be readily understood upon referring to the drawings, 'in which- A indicates a C-shaped frame havingbear- "through which motion is imparted by belt to said shaft, and it also carries apinion a, which, meshing with a gear-wheel b on shaft 0, gives motion to the latter, the relative sizes of the pinion a and gear 1) being such as to produce a differential speed of the two shafts, the quicker speed being given under the arrangement shown in the drawings to the upper shaft. The arrangement may obviously be reversed, however; but in such case the relation of the pressing or ironing and the work supporting or sustaining Wheels should likewise be reversed. These and similar minor points of constructionas, for instance,

in the form of the frame, the character of the belt-wheel, and the plane of the wheels belong to the province 'of the mechanic and may be Varied at will.

The lower shaft C carries at its forward end and outside of frame A a Wheel or disk E, keyed or otherwise made fast upon the shaft, and havingin its periphery a transverse notch or seat 0, (one or more.) Closely encircling the wheel or disk E is a hoop or band F, preferably though not necessarily of brass, having a rib or lug (1 (one or more) to fit the seat or seats 0, formed in the periphery of the disk, the interlocking of these parts causing the hoop or band to turn with and as a part of the Wheel or disk E. The band may be fastened in place in any convenient manner, more friction being sufficient if the band be closely fitted and firmly pressed to place; but a firmer hold being secured by very slightly heating the band and permitting it to shrink upon the disk. 0

The reason for making the hoop or band removable is that some seams have a welt introduced between the parts joined, while others have not, and when operating upon welted work a groove is necessary in the supporting 5 hoop to receive the welt, while for plain work such groove is undesirable. By making the hoops or bands interchangeable I render one machine capable of working upon different kinds of seams. IOO

The upper shaft B is made in two parts or sections 6 and fthe former carried in fixed bearings in frame A and the latter carried at its outer end in a swinging or adjustable box or bearing 9', mounted upon a rock'shaft G, which is supported in suitable ears or bearings in the frame A, parallel with, but at one side of, shaft B.

Projecting from the rock-shat t G is an arm or lever G, by which it may be rocked to lift the free end of the swinging bearing or box g, and consequently the shaft B, against the pressure exerted by a spring H, secured at one end to frame A, and bearing at its other end upon the swinging box.

The pressure of the spring His adjusted by means of a screw I, passing through a web of frame A and bearing upon the spring H, as shown in Figs. 1 and 3, and the descent of the swinging bearing or box, and consequently of shaft B, is determined by a stopscrew J, passing through a suitably-threaded hole in frame A and bearing at its end against the lever G, as also shown in Figs. 1 and 3.

The two sections 6 and f of shaftB are kept from slipping out of proper relation by forming one with a conical socket h and the other with a conical point of slightly more acute angle than the socket in which it is seated, the difference in angle permitting the slight movement necessary to the section f. The sections are connected by a strong spiral spring K, wound about their proximate ends and made fast to each a short distance from such ends, as shown in Figs. 1 and 5.

L indicates the pressing or ironing wheel, carried at the outer end of shaft B, directly in line with wheel E and its hoop or band. This wheel is preferably formed of or bound with brass; but as its surface is the same for all classes of work it is not necessary or desirable to make the ring or hoop removable in the event of its being separate from the body.

WVhen the machine is to be used, the screw J is set to bring the peripheries of the wheels E L (or of their rims) into close proximity, but preferably not into actual contact, the adj ustment depending, however, upon the stock to be passed between the wheels.

M indicates a seam-guide, the stem or shank j of which plays freely through a guidingarm or support N, projecting from the frame A, the guide being free to rise and fall as the work requires. To prevent the guide from turning laterally, it is furnished with two cars Z, between which the edge of wheel L passes, as indicated in Fig. l. A guiding rib or feather may also be applied to the shank or stem j, if desired.

The lower end of the guide M is bifurcated, as shown in Fig. 4, audits two members made thin enough to be quite elastic and to yield to comparatively slight pressure. The slot or opening between them is beveled, as shown in the same figure, to facilitate the entrance of the seam between them, and their ends are so fashioned as to extend well up into the bite or angle of the wheels or rollers, so as to carry the scam in an upright position direct] y to the pressing or ironing point.

Under former constructions the seamguide has been bifurcated and made with elastic members; but the members have been fashioned to spring from each other andhave been held in fixed relation by an ad j ustingscrew swiveled in one and threaded into the other near their lower ends. Such construction prevented any yielding action of the members while the machine was in operation, and consequently the guide was not infrequently bent or broken or the stock in jured by it. My construction, on the other hand, gives constant and adequate support, but permits the prompt and easy separation of the members to allow the passage of knots, cross-seams, or other enlargements. By this provision and by arranging one wheel or roller so that it may move away from the other at all times in the event of a thicker body pass ing through than the machine is primarily adjusted for, I avoid the two sources of difficulty experienced with prior machines, the second of these difiieulties being the breaking of the seams by undue pressure due to the unyielding support of the rollers and the consequent excessive pressure put upon thick portions.

I do not mean to restrict myself to the precise details shown, and may, for instance, arrange the supporting instead of the ironing roll to yield, or both may be so arranged. So, too, a continuous shaft may be substituted for the two-part shaft B, suitable bearings and gearing already well known to mechanics being adopted to afford the requisite movement.

Having thus described my invention, what I claim is 1. In a machine for pressing seams, the combination of a work-supporting roller and an ironing-roller, the former having its working-face or periphery formed by a removable hoop or band, substantially as and for the purpose specified.

2. In combination with-a suitable supporting-frame and with shafts mounted therein, an ironing roller or wheel carried by one of said shafts, a supporting-roll carried by the other shaft, and a removable band encircling the supporting-roll and constituting the workin g-surface thereof.

3. In a seam-pressing machine, the combination, with a work-supporting wheel and an ironing-wheel, one movable toward and from the other, of a yielding support for the movable wheel, and an adjustable stop adapted, substantially as shown, to regulate the approach of the movable roll.

l. In a seam-pressing machine, the combination, with a work-supporting wheel and an ironing-wheel, one movable toward and from the other, of a yielding support for the mov- ITS able wheel, a spring acting upon said support, and a stop to limit the approach of the movable wheel.

5. In a seam-pressing machine, the combination, with a work-supporting wheel and an ironing-Wheel, one movable toward and from the other, of a yielding support for the movable wheel, a spring acting upon said support, means for varying the force of the spring, and an adjustable stop to limit the approach of the movable Wheel.

6. In a seam-pressing machine, the combination, with the main frame, of the shaft 0, journaled therein and provided with a worksupporting Wheel, a divided shaftB, journaled at one end in the frame, and provided at its outer end with an ironing-wheel, a rocking bearing for the free end of the divided shaft,

and gearing connecting the shafts.

7. I11 a seam-pressing machine, the combination, with the main frame, of the shaft O,

' journaled therein and provided with a worksupporting wheel, a shaft B, comprising two parts 6 and f, connected bya coiled spring K, the part 6 being journaled in the frame and the part f being provided with an ironing- Wheel, a rock-shaft journaled in the frame, and a box or bearing carried by the rockshaft and adapted to receive andsupport the part f of the divided shaft.

' 8. In combination with frame A, shaft 0, provided with a work-supporting wheel, a divided shaft B, provided with an ironingwheel, a rock-shaft G, provided with a beariug for the end of shaft B, and an arm G, a screw J, adapted to bear against the arm, a spring H, secured to the frame and adapted to bear upon the movable box or bearing,,and a set-screw I, for varying the tension of the spring.

9. In a seam-pressing machine, the combination, with a main frame and the work-supporting and ironing wheels, of aseam-guide provided with ears, as Z Z, to embrace the ironing-wheel to prevent wabbling.

In witness whereof I hereunto set my hand in the presence of two witnesses.
